ext4: fix invalid inode checksum (2020-10-21 23:22:38 -0400)
----------------------------------------------------------------
The siginificant new ext4 feature this time around is Harshad's new
fast_commit mode. In addition, thanks to Mauricio for fixing a race
where mmap'ed pages that are being changed in parallel with a
data=journal transaction commit could result in bad checksums in the
failure that could cause journal replays to fail. Also notable is
Ritesh's buffered write optimization which can result in significant
improvements on parallel write workloads. (The kernel test robot
reported a 330.6% improvement on fio.write_iops on a 96 core system
using DAX[1].)
Besides that, we have the usual miscellaneous cleanups and bug fixes.
